but that ... hasten

[sakya kim]

in this following contexs, should it be: the clause ''he taught'' between the words ''but' and 'that' ?
And can the verb ''hasten'' have imperative meaning in this context?

Thanks to All.

The contexts:

And the rising and falling is produced by the transmission of force originally generated by wind. Just so the Buddha did not teach that it is an ego-entity, or a soul, that hastens through the ocean of rebirth, but that it is in reality merely a life-wave which, according to its nature and activities, appears here as man, there as animal, and elsewhere as invisible being.

No, it doesn't need to be inserted there because the structure of the sentence implies it. "He didn't teach this, but that." = "He didn't teach this, but [he taught] that." This is normal and it would be redundant to repeat "he taught."

And can the verb ''hasten'' have imperative meaning in this context?

No. I wonder why you would think so? The sentence structure doesn't support an imperative meaning, and the verb is conjugated in the third person to agree with "ego-entity"/"soul." The imperative form would be hasten.
